We believe that this is a difference between J2SE 5.0 and Java SE 6.

It seems that way ...

On 64-bit Intel machines, all Web Start launching goes though the Java SE
6 deploy.jar and javaws.jar, even if it is targeting an older JVM and set
of runtime classes. On 32-bit capable hardware all Web Start launching
goes though the J2SE 5.0 deploy.jar and javaws.jar.

In the J2SE 5.0 Web Start classes, changes were made to how resources are
loaded from the Web Start cache, which we integrated directly. If
possible, can someone test on Windows to see if this issue reproduces
with the latest version of J2SE 5.0 (not Java SE 6).

I just did. I installed 1.5.0_16 under Windows XP SP 3 and made sure that it's used for JNLP. We show the version that's used in the About Box, so I could verify that it was indeed being used. And it worked fine. So this issue appears to be Mac-only.

This issue is a known Sun issue with the 1.5.0_16 deploy classes : http://bugs.sun.com/view_bug.do?bug_id=6746185

We found that on Windows in order to use the 1.5.0_16 deploy classes the 1.6 JRE has to be removed.

So with JRE 1.6.0 removed we were able to reproduce this issue with Sweet Home 3D on Windows (the help images do not load), as well as another game called Pox Nora.

We are currently investigating a work around that involves altering the URL of the resource that is being requested.

Still investigating,
